(a) the criminality of an offender must be assessed by reference to the involvement of the offender in the steps taken to effect the importation;
(b) offences of attempting to possess imported drugs are not, for that reason, in a less serious category than that of importing drugs;
(c) it is often difficult for a sentencing court to attempt to categorise the offender's role in the drug enterprise, as in many cases the full nature and extent of the enterprise is unlikely to be known to the court;
(d) the fact that another person may be characterised as the "mastermind" does not mean that a person who was responsible for managing the importation into Australia is properly described as having only a middle level of responsibility;
(e) although the weight of the drug imported is not the principal factor to be considered when fixing sentence, the size of the importation is relevant and has increased significance when the offender is aware of the amount of drugs imported;
(f) it should be inferred, unless there is evidence to the contrary, that a person who is importing drugs is doing so for profit;
(g) the difficulty of detecting importation offences, and the greater social consequences that follow, suggest that general deterrence is to be given chief weight on sentence to signal to would-be drug traffickers that the potential financial rewards to be gained from such activities are neutralised by the risk of severe punishment;
(h) involvement at any level in a drug importation offence must necessarily attract a significant sentence, otherwise the interests of general deterrence are not served;
(i) the prior good character of a person involved in a drug importation offence is generally to be given less weight as a mitigating factor on sentence.
